ClassImp is a macro defined in Rtypes.h. It can be written without trailing
semicolon. However, clang-format is based on lexing and it doesn't know at
all about preprocessors and how to expand macros. When visiting ClassImp(X)
it thinks this is not a completed entity (as it doesn't expand macros) and
considers the next line as continuation of the previous.

Inserting a semicolon fixes the issue and makes formatting with clang-format
in the ROOT codebase less tricky.

This reverts commit b406328d, reversing
changes made to 318c7a47.

TProofPerfAnalysis internally creates temporary histograms or graphs for basic visualisation.
This patch adds the possibility to save these objects to a file for further usage, for example
to create more elaborate plots.

Saving is enabled by a call to SetSaveResult, which can be used to change file and/or to disable:

    root [] TProofPerfAnalysis paf("perf_analysis_output.root")
    root [] paf.SetSaveResult()
    Drawn objects will be saved in file 'results.root'
    root [] paf.RatePlot()
    root [] paf.SetSaveResult("results-global.root", "UPDATE")
    Drawn objects will be saved in file 'results-global.root'
    root [] paf.RatePlot()
    root [] paf.SetSaveResult(0)
    Drawn objects saving disabled

An object was invalidated going out of scope of the calling function(s)
TProofBench::RunCPU and TProofBench::RunCPUx.

  Scalability for multicores with hyperthread enabled shows a shape with a kink corresponding
  to the transition from the 'real core' to 'hyperthread core' regime. The available functions
  used to model scalability can be modified to include this effect in the simplest way.
  A new fit option has been added to TProofBench::DrawCPU and TProofBench::DrawDatSet, with the
  possibility to indicate the number of real and hyperthreaded cores.

  PROOF queries show a maximum processing rate at regime related to the processing
  power of the cluster. This patch patch measures this maximum and stores together
  with the average rate, which includes end-of-query overhead.
  Average and maximum are now swon on the plots and TProfiles for the two set of
  values saved in the output files.

  Add possibility to switch off constructor verbosity; introduce a separate member variable
  for single methods verbosity.

  Add new functions (FileRatePlot, FileProcPlot, PrintFileInfo) to extract the information
  per processed file.
  In RatePlot, add possibility to plot the total instantaneous and average rate.
  Add function Summery to show a summary of the query with a comptact frm option convenient
  for saving in text files.

   In TProofBench::DrawCPU and TProofBench::DrawDataSet, fix an issue with histogram range when
   the range was not starting from 0.
   In TProofBenchRunDataRead::Run, allow starting from Nwork > 1 also for the Nx case.

Replace the trunk code that uses the deprecated TH1::kCanRebin bit with
the new methods TH1::CanExtendAllAxes() and TH1::SetCanExtend() - see r47909,
r48012 and r48031. The old TH1::kCanRebin bit did not really have much to
do with histogram rebinning, but rather with extending the limits of the
histogram's axes (which can cause a rebin, but only in some cases). As such,
the word "Rebin" has been replaced with "Extend" for the new methods.

Rename TH1::RebinAxis() to TH1::ExtendAxis() for the reasons stated above.
The TH1::RebinAxis() method will be kept in v6-00 for backward compatibility
with an obsolete warning and will be removed in v6-02. The current
implementation simply forwards the call to TH1::ExtendAxis().
